Wordpress layout for writing and editing posts has changed

The screen I use for creating and editing posts has changed. There are fewer text buttons and all the alignment buttons have gone so I cannot justify my text. My pictures won't show in editing mode either. This has happened in the past week. I want my old WordPress back. Help!

Two things; First, make sure you are not in the text editor. There are two buttons at the top right of the editor screen, Visual, and Text. Make sure you click Visual.

Second, do you only see one row of buttons above the visual editor? If so, you may have accidentally turned the second row (called the kitchen sink) off. To turn it back on, simply click the last icon on the right, and the second row should appear.
